For example, to receive, mate with and be compatible with the magazine 142, the user can slide, rotate or otherwise move one or all of the adjustable elements 85, 87 to a first position relative to the adaptive body 83. In this first position, the adaptive structure 81 is compatible with the magazine 142. In another example, to receive, mate with and be compatible with the magazine 146, the user can slide, rotate or otherwise move one or all of the adjustable elements 85, 87 to a second position relative to the adaptive body 83. In this second position, the adaptive structure 81 is compatible with the magazine 146. This functionality enables the loading structure 80 to be universally adjustable to accommodate a variety of different types of ammunition or firearm magazines 142, 146 without requiring the involvement of separate magazine adapters. In an embodiment, the adaptive structure 81 includes part or all of the structures, elements and functionality of the magazine adapters 134, 138, 140, 144. In an embodiment, the adjustable elements 85, 87 include one or more catches that are adjustable in a direction so as to achieve computability with a particular firearm magazine, such as a Sig Sauer™, Beretta™ or Glock™ magazine. For example, in this embodiment, a catch 154 (FIG. 11B) of the Glock™ magazine may mate and reversibly interlock with the adaptive structure 81. In other embodiments, the adaptive structure 81 may not include a catch, retention structure, or catching mating element, and the applicable firearm magazine may instead be retained within the adaptive structure 81 using a securement device 188 (FIG. 16).

In the example illustrated in FIGS. 10A-10C, a 9 mm Glock™ magazine adapter 134 is configured to partially receive and mate with a 9 mm Glock™ magazine 136. In the example illustrated in FIGS. 13A-13C, a Sig Sauer™ or Beretta™ magazine adapter 138 is configured to partially receive and mate with a Sig Sauer™ or Beretta™ magazine (not shown); In the examples described above, the magazine adapters 134, 138, 140 and 144 differ from one another in at least one physical or functional property or characteristic, so as to be co-operable or otherwise compatible with the different properties or characteristics of the associated firearm magazine. The compatibility advantage provides an important improvement, enabling users to use the firearm magazine loader 10 to load different types of firearm magazines.

In such embodiment, users can procure a kit of magazine adapters 134, 138, 140, 144 for use with the firearm magazine loader 10.

Referring to FIGS. 4 and 14A-21, in an example, the first step to use the firearm magazine loader 10, involves coupling the magazine adapter 134 to the loading structure 80. The loading structure 80 defines a loading space 89 (FIGS. 14A-14B), a plurality of coupling slots 178, 180, a magazine receiving space 182, an adapter securement slot 184 and a plurality of equally spaced-apart friction enhancers 186.

In this embodiment, the firearm magazine loader 10 includes a securement device 188, as illustrated in FIG. 16. The securement device 188, which is coupled to the loading structure 80, includes: (a) a securement member 189 configured to protrude through the adapter securement slot 184 and interchangeably engage the adapter retainer 192 (FIGS. 10C and 13C) of the magazine adapter 134 or 138; (b) a biasing member 193 configured bias the securement member 189 into engagement with the adapter retainer 192; (c) a grasp 194 configured to be moved between a plurality of positions; and (d) a pivot member 195 that pivotally couples the securement member 189 to the loading structure 80. The loading structure 80 defines a channel 197 that holds and receives the biasing member 193. Depending upon the embodiment, the biasing member 193 can include a compression spring, coil spring, elastic member or any other suitable type of bias generator.

As illustrated in FIGS. 10A-10C and 13A-13C, the body interface portions 148, 156 of the magazine adapters 134, 138, respectively, have a plurality of notches, protrusions or retaining members 192, 194. In addition, each of the magazine adapters 134, 138 defines a plurality of flex slots 196, 198 having a plurality of enlarged flex spaces 200, 202, respectively. The flex slots 196, 198 define a plurality of flexible sections 204, 206, respectively. The flex slots 196, 198 facilitate the flexing of the flexible sessions 204, 206 along the flex axis 208.

As illustrated in FIGS. 17-19, the user can squeeze the flexible sections 204, 206 together until the retaining members 192 fit within the magazine receiving space 182. Then, the user can align the retaining members 192, 194 with the coupling slots 178, 180, respectively. Next, the user can release the flexible sections 204, 206, at which point the flexible sections 204, 206 will elastically move away from each other until the retaining members 192, 194 move into the coupling slots 178, 180, respectively. In an embodiment, the flexible sections 204, 206 include a biasing characteristic, including, but not limited to, an elastic characteristic of the material used to construct the magazine adapter 134, such as a flexible or semi-rigid polymer.

Next, as illustrated in FIGS. 19-20, the user can insert an empty magazine 136 into the magazine adapter 134. In doing so, the catch 154 (FIG. 11B) interlocks with the catch mating element 152 (FIG. 10A). As the user pushes in the forward direction 210, the magazine 136 drives the magazine adapter 134 forward until the adapter retainer 192 (FIG. 10C) reaches the securement member 189 (FIG. 16). At that point, the securement member 189, biased in a vertical or upward direction 212 due to the biasing member 193, moves into the adapter retainer 192, establishing a reversible interlock, as shown in FIG. 20.

As illustrated in FIG. 21, to remove a magazine adapter 134 (carrying a loaded magazine 136) the user can pull upward on the grasp 194. This upward force causes the securement member 189 (FIG. 16) to move downward and out of the adapter retainer 192 (FIG. 10C). This frees the magazine adapter 134 for removal from the firearm magazine loader 10.

For loading purposes, however, the user will keep the magazine adapter 134 (carrying an empty Magazine 136) installed in the firearm magazine loader 10. Next, referring to FIGS. 22-32, the user can dump or pour a box or handful of ammunition cartridge units 214 into the receptacle 30. In an embodiment illustrated in FIG. 32, each ammunition cartridge unit 214 includes a rim end 216 defining an annular recess, a bullet end 218 and a tubular case 221 extending between the rim end 216 and the bullet end 218. The ammunition cartridge unit 214 has a length dimension 220. In an embodiment, the case 221 has a diameter 223, and the bullet end 218 is heavier than the rim end 216. For example, the bullet end 218 can have a higher density that the rim end 216. The bullet end 218 can be constructed of a solid lead core or a hollowed tip constructed of lead. As shown in FIG. 31, the ammunition cartridge units 214 can be oriented so that: (a) multiple ammunition cartridge units 214 simultaneously pass through the receptacle opening 88, which is partially defined by the agitator concave surface 222, as shown in FIG. 24; (b) the rim end 216 of any of the ammunition cartridge units 214 is oriented below or downward from the bullet end 218, wherein the ammunition cartridge unit 214 travels downward with the rim end 216 first; or (c) the bullet end 218 of any of the ammunition cartridge units 214 is oriented below or downward from the rim end 216, wherein the ammunition cartridge unit 214 travels downward with the bullet end 218 first.

Referring to FIGS. 33-34, due to gravity, the ammunition cartridge units 214 travel or move downward through the receptacle opening 88, into the primary input 70 and through the primary passage 68. As shown, the primary passage 68 is defined by the union or assembly of the intermediate body portion 62 with the upper panel 60.

Referring to FIGS. 35-43, the ammunition cartridge units 214 exit the primary passage 68 at the primary output 72. The cartridge positioner 35 is located at or below the primary output 72. As illustrated in FIGS. 41B-42B, in an embodiment, the cartridge positioner 35 includes: (a) a plurality of fingers 224, 226, 228 spaced apart by a plurality of gaps 230, 232; and (b) a ramp or downwardly sloped surface 234. When assembled, the intermediate guide surface 236 (FIGS. 33 and 40) of the intermediate body portion 62 and the positioner edge 238 of the sloped surface 234 define the secondary input 76, as illustrated in FIGS. 35 and 40.

In the embodiment shown in FIG. 36, the drive assembly 40 of the firearm magazine loader 10 includes an agitation driver 240 engaged with the agitator 34, the cartridge positioner 35, a lifting rod or lifter 242 coupled to the cartridge positioner 35, a primary arm or primary link 244, a secondary arm or secondary link 246, and a drive shaft 344, each of which is described below.

Referring back to FIG. 33, the agitator 34 is pivotally coupled to the receptacle 30 through a pivot member 248. The agitator 34 has a C-shape that partially defines the receptacle opening 88. Also, the agitator 34 has a V-shaped portion 250 defining a recess configured to receive an upper end 254 of the agitation driver 240. The upper end 254 engages the V-shaped portion 250 at a point that is offset from the pivot member 248. The lower end 256 of the agitation driver 240 has an L-shape defining a branch 258. A biasing member 260 (e.g., compression spring), when positioned within a cavity 262 (FIG. 47), applies a downward biasing force to the branch 258. As a result of such biasing force, the agitation driver 240 is predisposed to be positioned in a downward position, enabling the agitator 34 to pivot clockwise 262 (FIG. 33) under gravity or the weight of the pile of ammunition cartridge units 214. When the branch 256 is moved upward, as described below, the agitator 34 pivots counterclockwise 264, as illustrated in FIG. 33. During the agitation action, the agitator 34 frequently pivots in alternating clockwise and counterclockwise directions 262 and 264, respectively. If the receptacle 30 is filled enough with ammunition cartridge units 214, such as filled to the maximum fill line 270, the agitator head 266 and the agitator foot 268 will disturb, mix and apply forces to the ammunition cartridge units 214. In an embodiment, the agitator 34 includes an agitator grasp 271. The agitator grasp 271 extends from the agitator head 266. If the ammunition cartridge units 214 become jammed or obstructed within the receptacle 30, the user can grasp and move the agitator grasp 271 upward and downward to clear the obstruction.

As a result of the agitation action, one or more of the ammunition cartridge units 214 falls through the receptacle opening 88, as described above. Eventually, the one or more ammunition cartridge units 214 reach a screening or staging gap 272, as illustrated in FIG. 40. In an embodiment, the staging gap 272 has a staging dimension 274 that is: (a) greater than the diameter 223 of any single one of the ammunition cartridge units 214; and (b) less than double the diameter 223. Consequently, the staging dimension 274 only enables the ammunition cartridge units 214 to sequentially travel to the sloped surface 234. In other words, the staging dimension 274 ensures that the ammunition cartridge units 214 travel, one by one, to the sloped surface 234.

As illustrated in FIGS. 41A and 41B, when one of the ammunition cartridge units 214 reaches the sloped surface 234, the ammunition cartridge unit 234 is positioned, momentarily, in a horizontal position on the sloped surface 234. As illustrated in FIGS. 42A and 42B, the sloped surface 234 has a surface length 276 that is: (a) greater than the length dimension 220 (FIG. 32) of the ammunition cartridge unit 234; and (b) less than double the length dimension 220. The ammunition cartridge unit 234 can reach the cartridge positioner 35 with the bullet end 218 above the rim end 216 (FIG. 42A) or with the rim end 216 above the bullet end 218 (FIG. 42B). Depending upon the angle of entry, the ammunition cartridge unit 234 will land, momentarily, with the bullet end 218 facing in the rearward direction 278 (FIG. 42A) or with the bullet end 218 facing in the forward direction 210 (FIG. 42B). From there, the ammunition cartridge unit 234 will roll and pivot, under its own weight, so that the ammunition cartridge unit 234 slides off of the sloped surface 234 with the bullet end 218 positioned below the rim end 216, as shown in FIGS. 42A and 42B. This is because the bullet end 218 weighs more than the rim end 216. This ensures that all of the ammunition cartridge units 234 sequentially slide downward, leaving the cartridge positioner 35 with their bullet ends 218 oriented downward.

In an embodiment illustrated in FIGS. 33, 35 and 43, the firearm magazine loader 10 includes a unjamming device 280. The unjamming device 280 includes: (a) an L-shaped disturber 282 slideably coupled to the lower panel 54; and (b) a biasing member 286 (e.g., compression spring) coupled to the lower panel 54 that applies a downward biasing force to the disturber 282. The coupler 284 has a head or grasp 288. If the ammunition cartridge units 234 become jammed or obstructed within the primary passage 68, the user can move the grasp 288 upward and downward to disturb and reposition the ammunition cartridge units 234 to clear the jam.

As illustrated in FIGS. 44-49, when one of the ammunition cartridge units 234 leaves the cartridge positioner 35, the ammunition cartridge unit 234 enters the secondary input 76, which provides access to the secondary passage 74 which, in turn, leads to the secondary output 78. The secondary input 76, secondary passage 74 and secondary output 78 are defined by the union or assembly of the lower panels 54, 56. As shown in FIG. 46, the secondary input 76 has a funnel shape with a decreasing width. The tapered side surfaces 290 (FIG. 44) and 292 (FIG. 46) collectively direct the ammunition cartridge unit 234 to achieve a substantially vertical position while dropping downward until entering the secondary passage 74. Due to gravity, the ammunition cartridge unit 234 then falls downward through the secondary passage 74.

In the embodiment shown in FIGS. 44-45, the firearm magazine loader 10 has a director 293. The end or finger 295 of the director 293 is inserted through a slot 297 within the lower panel 56. If the ammunition cartridge unit 234 is not positioned vertically while dropping, the finger 295 of the director 293 engages the ammunition cartridge unit 234 to orient the ammunition cartridge unit 234 to have a vertical or substantially vertical position. Eventually, the ammunition cartridge unit 234 reaches the secondary output 78 (FIG. 46) and contacts the primary driver 36.

As illustrated in FIGS. 50A-53, the primary driver 36 includes: (a) a plurality of vertical guides 294, 296; and (b) a cartridge engagement surface 298 configured to abut and make physical contact with the bullet end 218 of the ammunition cartridge unit 234. The cartridge engagement surface 298 has a landing portion 300 and a ramp portion 302. As described below, the ramp portion 302 is configured to gradually increase the upward travel of the ammunition cartridge unit 234 as the bullet end 218 is laterally slid from the landing portion 300 to the ramp portion 302. The vertical guides 294, 296 are configured to fit into, and mate with, a plurality of vertical slots (e.g., vertical slot 304 shown in FIG. 48) defined by the lower panels 54, 56. Accordingly, the primary driver 36 is configured to slide upward and downward within the body 22 between a ready position 299 (FIG. 47) and a loading position 311 (FIG. 56).

With continued reference to FIGS. 50A-53, the secondary driver 38 has an elongated box shape including a cartridge engagement surface 306, a holder 310, and a biasing member 308 (e.g., compression spring) supported by the holder 310. A first end 312 of the biasing member 308 is coupled to the holder 310, and a second end 314 of the biasing member 308 is coupled to the lower panel 56 (FIG. 51). In operation, the biasing member 308 applies a biasing or spring force to the secondary driver 38. This spring force urges the secondary driver 38 toward a ready position 309 wherein the secondary driver 38 is cleared outside of the secondary passage 74, enabling an ammunition cartridge unit 234 to fall through the secondary passage 74. The cartridge engagement surface 306 has a concave shape to correspond to the tubular shape of the ammunition cartridge unit 234.

As shown in FIG. 52, the lower panel 56 defines a horizontal cavity or horizontal slot 316 configured to receive the secondary driver 38. The slot has a plurality of horizontal guide surfaces 318, 320 configured to slideably engage the secondary driver 38. Accordingly, the secondary driver 36 is configured to slide laterally within the body 22 between the ready position 309 (FIG. 52) and a loading position 311 (FIG. 56).

Referring to FIGS. 53-54, the primary link 244 includes: (a) a wheel or primary gear 322 having a primary pivot member 324 pivotally coupled to the lower panel 54 (FIG. 44) for support purposes; and (b) a primary extension 326 extending from the primary gear 322. The primary extension 326 is configured to fit into the primary driver recess 328 defined by the primary driver 36. Depending upon the embodiment, the primary extension 326 can be pivotally coupled to the primary driver 36. The primary gear 322 has: (a) a primary driver peak 330 and a primary driver tooth 332 separated by a primary valley 334; and (b) a primary stoppage peak 336 separated from the primary driver tooth 332 by a primary valley 338.

With continued reference to FIGS. 53-54, the secondary link 246 includes: (a) a wheel or secondary gear 340 defining an opening 342 configured to be receive and be fixedly coupled to the drive shaft 344; and (b) a secondary extension 346 extending from the secondary gear 340 and configured to engage a secondary driver member 348 (FIG. 53) of the secondary driver 38. The secondary gear 340 has a secondary driver peak 400 and a secondary driver tooth 402 separate by a delay valley 404.

Referring to FIGS. 53-57C, in an embodiment, the actuator 42 includes a handle 406 fixedly connected to the drive shaft 344. Initially, the handle 406 is in the up or first handle position 408 as shown in FIG. 1B. The user can push the handle 406 downward in the counterclockwise direction 264 to achieve the second handle position 410 as shown in FIG. 55B. In the process of transitioning from the first handle position 408 to the second handle position 410, the secondary gear 340 is initially activated and rotated to in the counterclockwise direction 264. Referring to FIGS. 54 and 57A, in the first phase of the rotation, the secondary driver peak 400 engages the primary driver peak 330. As the rotation occurs, the secondary driver peak 400 applies a force to the primary driver peak 330 which causes the primary link 244 to rotate in the clockwise direction 262 which, in turn, causes the primary driver 36 to move upward, as shown in FIG. 57A. During this first phase, as illustrated in FIG. 57A, the secondary driver 38 remains in its original or substantially original position during the upward movement of the primary driver 36. This is due to the delay valley 404. The delay valley 404 has an arc length that stalls the engagement of the secondary driver tooth 402 with the primary driver tooth 332.

In transitioning from the first phase (FIG. 57A) to the second phase (FIG. 57B), the secondary driver tooth 402 slides along the delay valley 404 encountering no interference, which avoids generating a lateral force on the secondary driver 38. This results in an important time delay between the driving action of the primary driver 36 and the driving action of the secondary driver 38. Because of this time delay, a single actuation of the actuator 42 can result in the following: (a) an upward force (operable to move the ammunition cartridge unit 234 upward next to the magazine mouth or magazine opening 412); and (b) a horizontal or lateral force (operable to move the ammunition cartridge unit 234 laterally through the magazine opening 412) that occurs a period of time after the upward force.

During the second phase, as shown in FIGS. 54 and 57B, the secondary driver tooth 402 applies a force to the primary driver tooth 332. The counteractive force of the primary driver tooth 332 causes the secondary link 246 to rotate in the clockwise direction 262, which, in turn, causes the secondary driver 38 to move laterally toward the magazine opening 412. In this position, both the primary driver 36 and the secondary driver 38 are engaged with, and applying forces, to the ammunition cartridge unit 234.

During the third phase, as shown in FIGS. 54 and 57C, the secondary driver tooth 402 continues to rotate and apply a force to the primary driver tooth 332. The continued counteractive force of the primary driver tooth 332 causes the secondary link 246 to further rotate in the clockwise direction 262, which, in turn, causes the secondary driver 38 to further move laterally toward the magazine opening 412. In this position, both the primary driver 36 and the secondary driver 38 are engaged with, and simultaneously apply forces, to the ammunition cartridge unit 234. As shown, the primary stoppage peak 336 applies a stopping force to the secondary link 246 while the secondary driver tooth 402 continues to rotate and apply a final force to the primary driver tooth 332. This final force causes the ammunition cartridge unit 234 to move entirely within the magazine 136. In an embodiment, during the conveyance of this final force, the primary driver 36 is in upward motion while the secondary driver 38 is stationary.

The dimensions and geometry of the delay valley 404 are set and configured to synchronize the movements of the primary driver 36 and the secondary driver 38. Based on such synchronization, when the ammunition cartridge unit 234 reaches the position near the magazine opening 412, the primary driver 36 and the secondary driver 38 are configured to simultaneously apply upward and horizontal forces to the ammunition cartridge unit 234 to effectively load the ammunition cartridge unit 214 into the magazine 136.

In an example shown in FIGS. 12A-12C and 58-62, the magazine 136 houses a compression spring 414. The magazine 136 includes a follower 416 coupled to the spring 414. The magazine 136 also includes an ammunition retainer or cartridge retainer 418 which, in this example, includes a plurality of retaining lips 420, 422. As illustrated in FIG. 59, in the first step of loading, the primary driver 36 applies an initial upward force 424 to the ammunition cartridge unit 234. As illustrated in FIG. 60, in the second step of loading, delayed from the first step, the secondary driver 38 applies an initial horizontal or lateral force 426 to the ammunition cartridge unit 214 while the primary driver 36 continues to apply the initial upward force 424, as shown in FIG. 60. The lateral force 426 presses the ammunition cartridge unit 214 against the follower 416 causing the spring 414 to compress, which, in turn, causes the ammunition cartridge unit 234 to become entrapped by the retaining lips 420, 422. As illustrated in FIG. 61, in the third step of loading, the primary driver 36 applies a final upward force 428 which causes the ammunition cartridge unit 234 to entirely pass through the magazine opening 412 and become fully positioned within the magazine 136.

As illustrated in FIG. 62, the forces generated by the primary driver 36 act along a primary axis 432, which extends in a primary plane 434. It should be appreciated that, depending upon the embodiment, the primary axis 432 can be vertical, substantially vertical or upwardly angled. The forces generated by the secondary driver 38 act along a secondary axis 436, which extends in a secondary plane 438. It should be appreciated that, depending upon the embodiment, the secondary axis 436 can be horizontal, substantially horizontal or laterally angled.

Referring back to FIGS. 36-38, 47, 56 and 57A-57C, the drive assembly 40 includes the lifting rod or lifter 242, among other components. As shown, the lifting rod or lifter 242 is connected to the cartridge positioner 35. The lifter end 430 is located within the primary passage 68 above the primary driver 36. When the handle 406 is in the up or first handle position 408 (FIG. 1B), the primary driver 36 has the ready position 299 (FIG. 57A). As shown in FIG. 57A, the lifter end 430 is spaced apart from, and located above, the primary driver 36 in the ready position 299. When the user moves the handle 406 to the second handle position 410 (Fig. FIG. 55B), the primary driver 36 moves upward to the loading position 301 (FIG. 57C). In the loading position 301, the landing portion 300 of the primary driver 36 makes contact with, and pushes upward on, the lifter end 430. This causes the lifter 242 to move upward, which causes the cartridge positioner 35 to move upward, which causes the agitation driver 240 to move upward, which causes the agitator 34 to pivot, which causes the agitation or mixing of the pile of ammunition cartridge units 214 within the receptacle 30, as illustrated in FIG. 38. When the user releases the handle 406, the biasing member 308 (FIG. 51) urges the secondary driver 38 to the ready position 309, which urges the handle 406 to the first handle position 408 (FIG. 1B). As described above, in this embodiment, the drive assembly 40 operatively couples the actuator 42 to the agitator 34, primary driver 38 and secondary driver 38.

Accordingly, as illustrated in FIG. 63, the actuator 42 is operable to generate a single input. Depending upon the embodiment, the single input can be a rotational movement, a translational movement or a combination thereof. Though the actuator 42 is illustrated in FIG. 1A as having a manually-operable handle 406, it should be appreciated that the actuator 42 can electrically generate the movement without the inclusion of a handle. For example, the actuator 42 can include a motor, solenoid or pneumatic device powered by a rechargeable battery or electricity supplied through an electrical cord. In such embodiment, the actuator 42 includes a switch, button or activation device operable to activate the electrical actuator 42. In any case, whether the actuator 42 is manually or electrically-configured, the actuator 42 generates the single input. Because the drive assembly 40 operatively couples the actuator 42 to the agitator 34, the primary driver 36 and the secondary driver 38, the single input has multiple outputs. The outputs are synchronized to apply differently-angled forces to the each ammunition cartridge unit 214 at designated times, all while agitating the ammunition cartridge units 214 within the receptacle 30.

Referring to FIGS. 64A-64B, each incremental movement of the actuator 42 (e.g., each downward travel of the handle 406) causes a single ammunition cartridge unit 214 to move into and be loaded within the magazine 136. As the ammunition cartridge units 214 are driven into the magazine 136, the magazine spring 414 is further compressed. When the magazine 136 is fully loaded or loaded to the user's satisfaction, the user can pull upward on the grasp 194, as illustrated in FIG. 65. Next, as illustrated in FIG. 66A, the user can pull the magazine 136 rearward. Since the magazine 136, at this point, remains interlocked with the magazine adapter 134, the retraction of the magazine 136 causes the magazine adapter 134 to pull outward, as illustrated in FIG. 66B. Finally, the user can detach the magazine 136 from the magazine adapter 134 because the interlocking is reversible, as illustrated in FIG. 67A. As illustrated in FIG. 67B, the loaded magazine 136 is then ready for installation into a firearm for shooting. By squeezing the magazine adapter 134, as described above, the user can detach the magazine adapter 134 from the loading structure 80, as illustrated in FIG. 67B.

In the foregoing description, certain components or elements may have been described as being configured to mate with each other. For example, an embodiment may be described as a first element (functioning as a male) configured to be inserted into a second element (functioning as a female). It should be appreciated that an alternate embodiment includes the first element (functioning as a female) configured to receive the second element (functioning as a male). In either such embodiment, the first and second elements are configured to mate with or otherwise interlock with each other.
